Yes!
My TB extension harness still gives me limp mode at random/unpredicable times and has for years now. Might be fine for 6 months then plays up 2 or 3 times in a shorter (days/weeks) succession.
I still don't believe there is a proper fix for this including replacing the ext harness with a newer (upgraded) one from Stillen. Very annoying and unsafe!
